Publication number: 20080306625Abstract: A dual-phase virtual metrology method is disclosed for considering both promptness and accuracy by generating dual-phase virtual metrology (VM) values, wherein a Phase-I conjecture step emphasizes promptness by immediately calculating the Phase-I virtual metrology value (VMI) of a workpiece once the entire process data of the workpiece are completely collected; and a Phase-II conjecture step intensifies accuracy, which does not re-calculate the Phase-II virtual metrology values (VMII) of all the workpieces in the cassette until an actual metrology value (required for tuning or re-training purposes) of a selected workpiece in the same cassette is collected. Besides, the accompanying reliance index (RI) and global similarity index (GSI) of each VMI and VMII are also generated.Type: ApplicationFiled: July 18, 2007Publication date: December 11, 2008Applicant: National Cheng Kung UniversityInventors: Fan-Tien Cheng, Hsien-Cheng Huang, Chi-An Kao

Patent number: 7457236Abstract: A method for providing an application cluster service (APCS) with fault-detection and failure-recovery capabilities. This method is composed of the steps of nodes clustering, invoking and detecting applications, fault-recovery of applications, detection of nodes, and node replacement. This method is applicable in a clustered environment to detect if a slave node is failed by sending a heartbeat periodically from a master node; and to detect if the master node still exists by checking if the master node stops sending the heartbeat (i.e. the master node may be failed).Type: GrantFiled: April 15, 2005Date of Patent: November 25, 2008Assignee: National Cheng Kung UniversityInventors: Fan-Tien Cheng, Shung-Lun Wu, Ping-Yen Tsai

Patent number: 7003367Abstract: An equipment management method for managing semiconductor equipment via an equipment manager. In the equipment management method, production scenario rules and equipment behavior rules are first defined respectively in a production scenario database of a configuration controller and an equipment behavior database of an equipment driver. Them, a command is received from a manufacturing execution system (MES), and is converted into a production process scenario by looking up the corresponding production scenario rule in the production scenario database. Thereafter, the production process scenario is converted into a GEI (generic equipment interface) message with a GEI message specification, and the GEI message is transmitted to the equipment driver. Then, the GEI message is converted into equipment communication messages regulated by an equipment communication protocol by looking up the corresponding equipment behavior rule in the equipment behavior database.Type: GrantFiled: September 24, 2002Date of Patent: February 21, 2006Assignee: National Science CouncilInventors: Fan-Tien Cheng, Chun-Yen Teng
